bels triumph 1200 daytona streetfighter


The term "Streetfighter" appears to have been originally coined by two drag racers, Odgie and Lil' Mark, whilst they worked at BSH (Back Street Heroes magazine) in the early 1990s. They applied the term to motorcycles which were modified to enhance their performance and handling, as opposed to the custom scene which preferred style over outright ability. The term has since been diluted somewhat, and is now regularly applied to any bike with motocross style handlebars, no fairings or other typical customizations. In recent years, the term has also come to be applied to motorcycles manufactured without fairings in this style, usually based on the same engine/frame combination as an equivalent fully-faired motorcycle in the manufacturer's product line-up.

Currently, Race Replicas like the Suzuki GSX-R Series and the Honda CBR series, that have been damaged in accidents or through hooliganism are generally the starting basis for a Streetfighter. The GSX-R 750 was initially often favored, due to its light weight and flexible engine. A side effect of the use of the 1980's GSX-R was the retention of the dual headlights in the subsequent streetfighter, and most Streetfighters stay based on Japanese machines.

Streetfighters are associated with riders who usually exhibits a gross general neglect of traffic regulations.

Martek Performance was a Motorcycle Engineering Company that was around from 1995 to 2003, and was in the same vein as Spondon Engineering. Their bikes have a major following in the Streetfighter world and are incredibly rare. Although this one keeps the main Triumph frame tube, everything else is a one off. Every piece that Martek made is a work of art.

I wanted a Streetfighter, but wanted something different. When this Martek Special came up I knew it was for me. This is the first half decent Streetfighter that I have seen based around a the 1200 Triumph engine. Rather than just take the fairing off of a Daytona, this was a beautiful, if half finnished project.

I bought the bike without even seeing it or hearing it run. I was told that the engine had been blue printed but had no way of confirming if it was or not, but the cyclinder head is definitely gas flowed, so it had been apart at some time. I fitted a new Hayubusa battery into the hand made battery box, tidied up the wiring the best I could, fitted a set of standard coils and standard but rejetted carbs. After about 15 minutes of fiddling around the engine burst into life and sounds very sweet; a slight water leek from one of the hoses, but that was the only problem - no bad rattles or noises to cause concern.

Update: 21 May 2008
I rode the bike for the first time and found a couple of thing, and a list of jobs that need doing:
  • The forks hit the petrol tank, drastically limiting the turning circle. This will need to be modified.
  • The bike feels very nose heavy. This is possibly down to the length and geometry, old tyres and over long/hard re shock. This will probably be more difficult to solve.
  • The electrics still need a lot of work.
  • The fairing will need to be replaced at some time.
  • The back light has a clear white lens, which will either need red bulbs or be replace by an LED light.

Update: 22 July 2009
Progress has been slow, but a few things have been sorted:
  • The water hose has been replaced and she is now water tight.
  • I have started work on rebuilding the wiring loom to fit the bike. This has turned out to be a comparitively simple task.
  • The rear bulbs have neen replaced with red LED lamps, which looks good with the clear lens. I want to get clear indicators to match and look modern.

Update: 21 November 2011
A house move delayed things for a while, but now:
  • I have fitted a new wiring loom from end to end as the old one had an issue around the fuse box.
  • The Nitrous Oxide is wired in and fully functional, but the splitter and fogger nozzles have been removed. So at the moment it is for show only.
  • New fuel taps have been fitted to the tank. The left hand one is twin outlet and feeds the carbs, and the right hand one feed the additional fuel pump for the Nitous Oxide System.
  • The switch on the left hand handlebar turns converts the horn button to the Nitrous button.
  • The front fairing has been replaced by a Speed Triple look of twin lights and fairing to try and keep the Triumph family resemblance.
  • A new rear numberplate holder and LED indicators have been fitted.
  • A new Speedo and Rev Couter unit has been fitted.
